Kharagpur station to have Asia’s largest interlocking system

The Indian Railways will introduce Asia's largest Solid State Interlocking (SSI) system in Kharagpur on Sunday, which will aid in setting 800 train routes and ruling out collisions caused by cross movements. The ₹39-crore project will replace the Route Relay Interlocking (RRI) system, through which operators were able to set only 423 routes.
